Circuit arrangement for cooling combustion air of internal combustion engine of motor car, has charge-air heat exchangers that are thermally coupled with high-temperature circuit and low-temperature circuit respectively

摘要

The circuit arrangement (1) has a charge-air compressor (3) for compressing combustion air (V) and charge-air heat exchangers (11,13,19) for cooling the combustion air. The charge-air heat exchangers (11,19) are thermally coupled with a high-temperature circuit (4) and a low-temperature circuit (5) respectively. The high-temperature circuit is designed as a motor cooling circuit, and the low-temperature circuit is designed as an electrochemical cell. An independent claim is included for a method for operating circuit arrangement.
